I have a G48 MOS I picked up last Fall and it has the dull, grayish on the slide . From the images I'm seeing from retailers on the web, the new production versions shipping with the new 15 round mags appear to have the slick nDLC finish like the full size guns (and like the 43x/48 used to have). I'd like to get another 48 MOS and prefer the slick finish.

Anyone pick up a 48 with the new mags recently and have the slick finish on the slide?

Assuming this is a recent production 43X, slide looks dull gray to me and stays that way even after cleaning and oiling.  This gun came with the new 15rd mags. Serial is ALAUxxx.

New G48 15rd picked up this week appears to be the same finish as my G47.

Both are darker than my G43

Thanks Chowser & MJ11B4P. Yeah, I'm seeing some have the slick finish and some are still coming with the dull/matte finish like Chowser's 43x. I'm wondering why Glock is putting them out both ways and what determines the finish application?

Tagging @Marksman14 as I'm interested to know too.

ETA: My chalk gray 48 MOS slide purchased last October is Austrian.

I have one of each from 3-4 years ago and both have the identical shinny slick black finish.

The 43 I got last year has the rough grey finish. Same with the US made Gen4 19 I got this year...rough grey finish.

I dont like the shinny dark finish because it is very slick and wears off easily on bearing surfaces like the breach face or anyplace that the barrel rubs. The new shinny slick finish is pure shit compared to the old "frying pan" slick finish from 15 years ago. That still looks new after many years.

I think B serials are the Austia made and the A serials are USA made.

My A serial gray slide is USA made.

Except my Austria made is gray

Starting to seem like there's no rhyme or reason to which slide finish a 43x or 48 get.

I got an mos a few weeks ago. Serial number starts with "C", "austria" on the slide. It came with two 15-round mags, and The finish looks the same as all the other Glocks I've carried and owned since 1999.

The gen3 and early gen4 guns with the frying pan finish were awesome.

It was their best finish.

I can't stand Glock's nDLC finish. It's too slick and starts coming off immediately. I was glad when my last couple 43X's came with nitride only.

I've had very good experiences with the nitride Glock has been using for the last 10 years or so. Little to no wear after tens of thousands of rounds. This is one of my 17 Gen 4's when it hit 10,000 rounds. I've got a 19 Gen 3 with two slides (one original and one factory MOS) that looks the same with 6250 rounds on the original slide and 3750 rounds on the MOS slide. I've been shooting Glocks since 1989 so I've experienced all the finishes.
